Figure (i is a detached View ofthe crank B5, and post B6, attached tothe ends ofthe bars B3 and B4. Similar letters of reference indicatecorresponding parts in the several figures. '.lhis improvement relatesto mechanism for operating the rake, for the purpose of raking grainfrom the .platform of reaping machines. vThe apparatus is attached toand travels with the harvester, and is operated by the driving-wheelsof' the same by means of the pinion-A on the ax-le zu, whichis thrown inand out of gear with the apparatus which drives the rake. By thisapparatus the grain is raked from the platform and 'deposited on theground in gavels suiiiciently large to forma sheai'.v The constructionis simple, andv ean'be attached to different varieties of reapingmachines. l l y To enable others skilled in the art to whichmy'invention appertains to fully understand and use the same, I willproceed te describe it, in connection with the accompanying', drawings.v

The platform is 'constructed to permit the grain'to be swept oif at oneside, the gavel' being delivered on the ground in rear ofthedriving-wheels. The apparatus for operating the rake is mounted partlyonA the frame ofthe reaping machine and partly under the platform, in abox or recess made to -reccive it, and partly on the side of theplatform next to the drivingswheel. -The shape of the platform beingcurvilinear, the movements of the rake are made to correspond therewith.As this application has exclusive reference to the devices by which therake is operated, I will limit .the description to such devices, andrefer to parts of the reaping apparatus only by way of elucidation. Thegear-wheel Ahas a tongue or key projecting inwardly in the hole, whichtsover the axle The wheel A is placed between the jaws of the lever L,and both are placed on the axle :c by passing them over the bud of thesame and moving them to their proper place. ThelaXle x has a groove orkey-seat cut lengthwise in one side, to receive the ltongue in the wheelA. Thev tongue is made to t loosely in the groove, so as to permit thewheel A to b'eshiftedV on the axle, whichchanges the movements of therake. The groove is cut in the axle suiiciently long to permit the wheelA t0 be moved to points opposite to the three different gear-wheels A2A3 und A@ so as to permit the pinion Al to be geared with either of themat the will of the operator. The pinion A*v is placed between the jawsof the lever L, in gear with the wheel A. The pinion Al has its journalsin the end ofthe lever L, which is pivoted onvth'c axle a', and servesto throw the pinion Al in and out 'of gear, l(see figs. and A2 A3 andA?, shown in.` gs. 1 Aand 4, are gear-wheels of different diameters,arranged on a shaft A5. The shaft A is placed in the frame of themachinein aposition parallel to the axle x, so as to place the gear-wheels in aproper position to be thrown in and out of gear with the wheel A on theaxle. The sliding-block M is arranged in the frame of the machine, inlfront of the axle x, on the rods I and Il, which lie parallel-with theaxle x. Thejaws of the block are extendedover the axle, one-on each sideof the lever L, and fitted closely to `the lever, and serve' to Vmoveit'with the wheel A along the axle in shifting the pinion A1 to changethe gear. The block is providcdwith aside-board or projection E, placedon one side of the block, extending upward sufficiently high to form aysegment of a circle, inwhich are holes or recesses, which formreceptacles for the projecting end of the lever lah-which tits intothem, and serves to hold the lever L in position, thus-holding thepinion Al in or out of gear with the gear-wheels on the shaft's. -Theblock M serves to move the wheel A on the axle, `and to jhold the leverL in position. When thelspced of the rake is to be changed, to increaseor diminish the size of the sheaf, it is done by grasping the top endsof the levers L and L1 in the hand, pressing them together, whichunlocks the lever L1 from'the recess in the side-board E, andv4 permitsthe lever to move round the axle, thus throwing the pinion Al out ofgear; then hy' pressing on the pin V, which presses down the spring'G,and unlocks the block from the rod l', the block 'may be moved, movingthe wheel Aand pinion A1 to the desired position the spring G throws itspoint into a notch in, the under sidev of the rod I, and locks .theblock so that it cannot move until it is unlocked by pressing down thespring; the levers-are grasped at the top, which unlocks the lever Ll;the tops of the levers are then thrown forward, which places thepinion-A1 in gear with a'wheel on the shaft B5. The end of the lever Lldrops into one of the holes or recesses Vin the projection E, and locks`the lever L, thus holding the pinion A1 in gear; by this means the rakemay be stopped or started, at'the will of the operator, andthe movementsof the rake can. be changed to suit different kinds of grain, and alsoto increase or diminish the size of the sheaf,vwhen the grain is heavyor light, Aas the casemay In fig; l Qthe pinion Al is represented asbeing in gear with the small gear-wheel A2. The three whcelsA Al and A2being all of the same diameter, andl having the same number of teeth orcogs when geared'together, causes the rake to deliver a sheaf to everyrevolution -of the 'driving-wheels, which may make a sheaf suicientlysmall for the heaviest grain, but could be made to work faster and makesmaller sheaves by making the wheel A2 smaller in diameter ;"the wheelA3 being once and a half larger than the pinion A1, and having once anda halt the number of teeth, causes the rake to deliver a sheaf at everyrevolution and a half of the driving-wheel; the wheel Abeing twice thediameter of the pinion, and having twice the number of teeth, causes therake to deliver a sheaf at every two revolutions `of the driving-wheels.The number of gear-wheels on the Vshaft Bs may be increased ordiminished, and their diameter changed if desired or found tobenecessary. A is a crank on the end of the shaft A5; `thewrist of thecrank husa sleeve or roller which turns on the wrist, for the purpose ofdiminishing friction; the roller ismade with a flange on itsend, whichlits into the yoke A7, and holds the yoke on the wrist, and permits .theyoke to vibrate on the rod A? when the wristof the crank -is Vworking inthe slot in the` yoke. VThe yoke is made with lugs on its lower end,having eyes Vor hol'es'through them, through which passes the rod AB;lthe yokeis secured in its position 4on the rod by means of collarsvwhich are fastened to the rod, and prevents the yokefrom movinglengthwise on the rod, but permits it to turnaround, vibrating' on therod when moving forward and backward; by this arrangement', theV yokeand rod can work freely, without interfering with the rotating of thecrank. The rod is'held in position at itsforward end by passingthrough-a hole in the projection Rand at its rear endby the end lofthevibrating arm A9to whichit is attached by'a hinge or vibrating'joint.The projection P is fastened to the under side of the connecting-bar C1,near its top* end.v The vibrating armA9 is pivoted near its middle totheunder side et' the bar C, which is hinged tothe frame of the machineat its top end,land to the platform at its lower end.

The arm. A9 is attached to the bar or link B by a double lvibratingjoint, thus making-the connection of the' parts of theapparatus on theframe of the machine withthe parts under and-'on the platform, (see iig.The bar B is attached tothel bar B by a'vibrating joint; l'l is pivotedto the platform, at a distance from the end attachedte the har B,'ofnear one-fourth itsflengt-h, (pivot'ma'rked F7) and at its other endtothe bar B. The bar B2 is pivoted at one end to the platform,`(pivothmarked IL) and at the other end tc the projection from the bar B4; oneend ofl the'bar B3 ispivoted to the har B2, at a distance from vtheinner end of 'the bar B2 of neary three-fifths its length; the otheren'dof the bar B3 is pivoted to the ond of the crank B5, which is attachedto and turns the post B6; the lower end ofthe post B6 is pivoted on` theend of the arm Bf, and is turned on the same by the crank B5, (see'ig.6.,' The end of the rake vB'I is .jointed tothe top 'ofthe postB andisz-turnedv amdvvoperat'ed` by the same. BS is a roller, on a projectionfrom the end of the rake,`whiel1 serves to elevate the rake while makingits ineffective stroke, and. also to hold it down tothe-,platform whilemaking its eifective stroken-(see fie. 2.) 4The devices by which therake is elevated and carried to the front of the platform are shown infigs. 1 and 2. S is a switch, forming an inclined plane, starting fromthe floor of the platform and `rising to the top of the track T; thetrack '.l is a board standing on its edge on the side of the platform,and serves as .a track to carry the'roller Bs, which' holds the rake inan elevated' position while passing to-,thc front of the platform, andalso serves as aside-board to prevent the grain from getting into thewheel 'or into the slot 4C); the roller B5 passing forward over theswitch Sl presses it down and forms a bridge, which carries the rollerover the eut oropening in the side-hoard; the switch Sl making aeon'tinuationof the track T; when the roller has passed forward oil' theend of the switch, the switch springs up, 'opening the cut intheside-,bearih the roller rests on the end of the board T2 until themotion is reversed andthe rake starts back to make its effective stroke;the roller Bs, rolling olf the end of the board. T2, passesdown'lthrough the cut or opening in thc'sidebcard, passing to the insideof the trackAT, causing ther-ako to descend to'theplatforin; the rollerrolls back `.to the rear, bearing against the edge of the track or boardTl, which serves .Ato-hold the rake downto the'platform while making itseffective stroke. T1 is a hoard laid dat on the platform, alongthe-inside of the track T, its edge forming a bearingfo'r the endofV theroller, while the rake is making its effective stroke, holding the rakedown tothe platform. When the rake has finished its eiectivestroke, ltheroller B8 has opened the switch S, and passed out from behind it, thespring S2 causes the'swlitch to spring -baclt to its place, falling inbehind the roller-4l and 'forming an inclined plane', which carries theroller up to the top of the track T, thus eleva'vtingthe rake, (see tig.2,-) prepa-ratoryto its forward movement. Whenl the rakestarts to makeits effective stroke itis thrown down to the platform vand immediatelymoves back over it, not stopping in the vwayof the falling grain. Thebox K is fastened to the platform or made in it, and serves te protectthe apparatus, which works underneath the platform the apparatus may bepivotcd to the bottomof the box or to the platform. O is a slot in theplatform to permit the post B6 to more forward and backward, from thefront to the rear of the driving-wheel, when the machine is in motion. lA

Having given a detailed description o f the construction and usesof thedifferent parts ofthe apparatus, I-

will proceed to describe its operation.

When the machine is in motion the axle :c turns forward, turning thewheel A with it, which being in gear with the wheel A1, causes it toturn backward, giving .it a reversed motion to that of the wheel A; whenthe wheel A? is in gear with either of the gear-wheels on the shaftB5,being on the under side of the gear-wheels and turning backward, itcauses the shaft to turn forward, which turns the crank A6 forward,carrying the yoke A7 and rod A5 with it; the rod AS being hinged tothetop of the arm A draws the top of thc-,arm with it. The arm A9 ispivoted near its middle to the connecting-bar C; when the top of the armis drawn forward it swings on its pivot, and causes the lower end of thearm to move backward, drawing the bar B with it; the bar B is hinged tothe end of the bar Bl, andv'draws the inner endof the bar Bl back also;the bar B1 being pivoted to the platform swings on its pivot, causingthe outer end to move forward toward the front of the platform, carrying the outer end of the bar .B4 with it; thebar B" -being pivoted atits bend or elbow to the outer end of the bar B, and at the end of itsprojection, to the han B2, is. operated by the bars Bl and B2; the barB2 being hinged at its inner end to the platform or bottom of the box K,and. at its outer end to the end ofthe projection from the bar B4. Whenthe innerend of the bar Bl is moved backward toward the .rear of theplatform, it swings on its pivot, its outer end moving forward, movingthe-bars B* and B2 forward with it. The'bar B2 holding out the endef theprojectionon the bar B4, causs the bar B4 to swing on its pivot on theend of the bar B1, which causes the inner end` of the bar B4-to moveforward, carrying the crank B5 with it, which also carries and operatesthe rake in its forward movement or ineffective 'strokegthebar B3 beingfastened'to the bar Bzat one end, and to the crank B5 at the other.-When the rake is beinglmoved forward by the'end of the bar B4, the b arB3 pushes the end of the crank around, causing the post Bs to turn onthe end of the bar-B4 5 when the post is carried to the front of theplatform, it is turned sufficiently to cause the rake to fall across thefront of the platform. When the movement of the yoke is reversed, therod A? moves backward, moving the upper end of the arm AD back, vandcauses the lower end of the ar'm to nieve forward, which moves the bar Band the inner end of the bar Bl forward; the bar B1 swinging on Aitspivot,V its outer -end inoves backward toward the rear of the platform;ythe bar B4, being pivoted on the end of the` bar Bl, is moved backalso;' the bar B2, being pivot-cdto the projectingcnd 'of the bar B4 atone end, and. to the platform at the other, causes the bar B4 to swingon its pivot on the end of vthe bar B1, moving its inner end, to whichthe post B G and rake are attached, back toward thc-rear ofthe platform,the rake'making its effective stroke; the bar B2 acting on the crank B5,pulls it around and causes the post B( to turn, which turns the rake,causing the outer end of the rake to swing around, performing a quarterof a circle, or nearly s'o, while moving from front to rear of theplatform, making its eifective stroke, thus sweeping the grain off ateneside of the platform, in rear of the driving-wheelst The apparatusworking underneath the platform is not exposed, being covered by theplatform, and protected by the door and sides of the box K, whichkeep-'out the dirt o'r stubble from the working parts of the apparatus;The bars lying on their' sides in the box K do not shake like uprightmachinery, and are not liable to get out of order, the rake being theonly piece -of machinery that 'is elevated, but not having a handle, itis not heavy and does not require much power to operate it. The bars ares" arranged in the box K as to cause the post B6 to move in the straightslot' O, at-the'side of the platform,'causing the end of therakeattached tothe post Bs to move from the 'frontto the rear of thewheel whil'e'the other end of the rake is swinging around over' theplatform. This movement will be understood by referring to figs. Zand 3.When the post Bl is moving backward and forward in the slot 0,'itis'being turned by. the crank B5, as before explained. When the rakemovesforward, the'roller B8 rollsup the switch Sento the. track T,elevating the rake. The rake being in an elevated position, the rollerBs crosses over the opening in the track or side-board on the switch orbridge` Sl, and moves on to the end -of the side-board marked T2, whereit rests and prevents the rake from .descending to the platform untilthe movement is reversed; when the rake starts to move backward, theroller rolls off the end of the side-board, passing through the opening,and v the ralge descends to the platform, falling into the buttsof thegrain, and continuing to'moveback' over the platform in its effectivestroke, sweeping the grain from the platform. When the rakef hasperformed its effective stroke the roller Bs, having opened the switchS, and passed out from behind it, the switch springs back into 'its'place, falling in behind the roller; when therakc moves forward theroller rolls up thc'switch, the top ofwhich forms an inclined plane, onto the track T,'elevatingv the rake, and rolls forward on vthe track T,and overthe switch S1, onfto the end of theboard T2, bringing the raketo the front of the platform, (see fig. 2.)v

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is 1. The gear-wheels A A1 AL A3 and A4, shaftB5, crank BG, lever L and L1, and block M, arranged to'operate in themanner and for thcpurpose substantially as described. v i 2.
